Do i have Enough Wattage?

[Cat_Returns]

i recently ordered my parts for my build. Did i make the correct choice in PSU for my build? Not sure if this matters on wattage usuage, but i am only going to overclock my graphics card (for now)

This is my PSU

With all you specified, you have enough wattage for cross fire. I wouldn't push past anymore than 5 hard drives though.

Your wattage use is around 349w.

I wouldnt want to go crossfire with that PSU. It only develops 30A on the 12v rails. But the system above should be fine.

thats great to hear. Theres so many bad information regarding PSU out there. Some people were saying that i needed above 650 for my build, which i knew was bogus.

i am curious, how did you get that calculation objecterror? i want to be able to calculate wattage need too!

Just from general knowledge and keeping up to date with the latest hardware, we can give estimates on what the average power draw of a system would be.

The system you linked could run on a 400watt quality psu, but its always better to go a little bit higher for more headroom/future expansion.
